00:00Microscopic polymer sheets respond to near-infrared light by self-folding into intricate origami structures.
00:07Doctors need tiny devices to navigate winding blood vessels without snapping or getting hopelessly stuck.
00:14Instead of bulky mechanical hinges, light-responsive polymer sheets fold themselves precisely at the microscale.
00:22Thermal expansion mismatches across the microscopic layers drive autonomous geometric transformation without external mechanical force.
00:31Upon exposure to near-infrared light, these microscopic polymer sheets dynamically fold to grip blockages inside vessels.
